A jury has been shown the fearsome-looking blade that the prosecution say was used to kill Derby dad-of-one Lance Martin.

The six men and six women also watched CCTV which prosecutors say shows a defendant disposing of it in a bin less than an hour after it was allegedly plunged into the back of the 24-year-old.

Footage shows a man the prosecution claim is Kieran Bareham put the handle of the kitchen knife down a storm drain in Rutland Street, just yards from the killing.

It then shows the figure place what prosecutors say is the blade in a blue bin outside a house on the opposite side of the street.

And the trial has also seen police body cam footage of the moment Bareham’s girlfriend, Francesca Butler, is arrested outside their home in Portland Street, Normanton, on suspicion of murdering Mr Martin.

Detective Constable Susan Sallis, the officer in the case, produced as exhibits the blade and the handle of the knife, which were passed around the jury.

CCTV was then played of a man she says is Bareham disposing of it.

DC Sallis said: “The handle is placed in a storm drain and was recovered by officers a week later after the CCTV was examined.

“You then see him lift the lid of a blue bin outside number 132 (Rutland Street) and place something inside it.

“That bin was also searched by officers and the blade of the knife was recovered.”

On the ground fighting

The prosecution claims Clara Butler is the person who stuck that kitchen knife four times into the back of Mr Martin while he was on the ground fighting with her father Jamie Butler.

Pathologist Dr Michael Biggs, who carried out the post mortem examination, told the trial how Mr Martin’s heart, lung and spleen were punctured and that any one of the fatal stab wounds could have caused his death.

“I have not done anything, I have been in the house all day, oh my God, Jesus.”

The trial has previously heard from PC Paul Marriott, who said he heard “a commotion” while he was in Pear Tree police station, close to the scene of the alleged murder, at around 1.10am on February 28.

'Let me help you'

He said: “I went outside and saw a man staggering towards me being followed by a second man who was saying ‘let me help you, let me help you’.

“I went to check he was alright, I asked him if he was okay and could see blood coming from his mouth.
